Assertion: Pneumonia is caused by the infection of Streptococcus pneumoniae. Reason: Streptococcus pneumoniae bacteria infect respiratory passage.
1 Both assertion and reason are true and reason is the correct explanation of assertion.
2 Both assertion and reason are true but reason is not the correct explanation of assertion.
3 Assertion is true but reason is false.
4 Both assertion and reason are false.
Explanation:
Streptococcus pneumoniae causes pneumonia. It infects alveoli of the lungs, not the respiratory passage.

Assertion: The malarial parasite requires two hosts to complete its lifecycle. Reason: These two hosts are human and mosquito.
1 Both assertion and reason are true and reason is the correct explanation of assertion.
2 Both assertion and reason are true but reason is not the correct explanation of assertion.
3 Assertion is true but reason is false.
4 Both assertion and reason are false.
Explanation:
The malarial parasite completes its lifecycle in two hosts, i.e., humans and mosquitoes. The female Anopheles mosquito works as a vector also.

Assertion (A) . Dengue fever is caused due to failure of clot reaction Reason (R) . The patient of dengue may require transfusion of blood platelets
1 Both $A$ and $R$ are true and $R$ is the correct explanation of $\mathrm{A}$
2 Both $\mathrm{A}$ and $\mathrm{R}$ are true but $\mathrm{R}$ is not the correct explanation of $\mathrm{A}$
3 $\mathrm{A}$ is true and $\mathrm{R}$ is false
4 $\mathrm{A}$ is wrong and $\mathrm{R}$ is true
Explanation:
B Dengue is not caused by the failure of the clotting reaction. It is caused by the dengue virus, which is transmitted to humans through the bite of infected Aedes mosquitoes, particularly the Aedes aegypti mosquito. The patient of dengue, symptoms are related to a decrease in platelet count and the virus's impact on blood vessels. So, he may require transfusion of blood platelets for recovering the disease.
